Putting waste avoidance at the top of our priorities means having to deal less with food disposal at the end. Landfills of food waste are a major source of methane gas, which also contributes to climate change.



Key elements of any robust solution will involve more sustainable packaging to ensure food safety along the supply chain. Particularly during transportation, the use of reusable packaging containers (RPCs) could further reduce food loss and waste. Above all, a clear understanding and commitment to the circular economy will be critical for success for the sake of the environment.

Solar-powered tricycles make a lot of business sense for Zimbabwe's small-scale farmers, since transport has always been inadequate in the sparsely populated rural areas of Zimbabwe, where women often had to walk long distances carrying heavy loads on their heads to trade products, which sometimes unfortunately spoilt on the way in the heat.



But the idea of addressing the problem with electric three-wheelers did not catch on quickly, said Shantha Bloemen, who is the director of the company who is assembling the off-road three-wheelers: "It was very lonely when we started," she said. "No one was talking about electric mobility in Africa let alone for rural women."



But after three years, the social enterprise is now planning to more than triple its current fleet of 88 motorised vehicles by the end of 2022, and already operates three solar-powered recharging stations.

In theory, satellites could continuously collect photons from the sun — converting the energy to photovoltaic cells, and wirelessly beam that electricity as radio waves back to receivers on Earth.



A space-based solar power station placed in Earth’s orbit would be illuminated by the Sun 24 hours a day allowing it to generate electricity continuously. This would give it a significant advantage compared with solar power systems placed on Earth, which can only produce electricity during the day and are heavily dependent on the weather.



As global energy use is projected to increase by nearly 50% by 2050, this method of generating power could play a crucial role in helping meet the growing demand and tackling the climate crisis.

“Forever chemicals” — also known as per- and polyfluoroalkyl substances or PFAS — break down slowly and accumulate in the environment and in human tissue, including in the liver, causing disease, according to a study published on Wednesday, 27th May 2022.



Thus far, scientists have determined a “probable link” between PFAS and diagnosed high cholesterol, ulcerative colitis, thyroid disease, testicular cancer, kidney cancer, pregnancy-induced hypertension, and liver damage.
